Thinking about buying a duplex, triplex, or small apartment building in Hattiesburg? You are not alone. Small multifamily can be a practical way to build income, but the right deal depends on more than a quick look at asking price and rent. If you want to get started in 39402 and the wider Lamar County area, this guide will help you understand the local market, key numbers, zoning basics, and the due diligence that matters most before you buy. Let’s dive in.
Hattiesburg offers a mix of renter demand, approachable property sizes, and neighborhood variety that often appeals to first-time investors and owner-occupant buyers alike. In 2024, Hattiesburg had an estimated 48,522 residents and 20,659 households, with an owner-occupied rate of 37.2%. That lower owner-occupied share points to a city market where renting plays a major role.
The city’s median gross rent was $1,005, while median household income was $46,342. Based on those figures, rent is about 26% of median household income, which sits below the 30% affordability benchmark used in Mississippi housing guidance. That does not guarantee performance for any one property, but it does help frame the local renter base.
Lamar County looks different from the city as a whole. The county had 66,734 residents, 25,381 households, an owner-occupied rate of 69.5%, median gross rent of $1,126, and median household income of $70,909. For buyers looking in 39402, that matters because county-level and citywide averages can point in different directions.
ZIP code 39402 stands out as a stronger-income submarket. It had 44,620 residents, 17,658 households, a median household income of $75,220, and a median owner-occupied home value of $253,900. That may support stronger rent bands than citywide medians, but you still need local lease-level data before making an offer.
In practical terms, many buyers use “small multifamily” to mean duplexes, triplexes, fourplexes, and small apartment buildings. These properties can work for different goals. You might want to live in one unit and rent the others, or you may be looking for a pure investment with several income streams.
In Hattiesburg’s land development code, a building with more than two dwelling units is considered an apartment house or multifamily dwelling. The city also has an R-2 Two-Family Residential district for duplexes and an R-3 Multi-Family Residential district that allows medium- and high-density residential uses, including multifamily, two-family, and single-family structures. That means property type and zoning are closely tied together from the start.
Before you tour properties, get clear on what you are actually trying to buy. A duplex in a stable pocket of 39402 may behave very differently from a small apartment building in another part of Hattiesburg. If your goals are not defined upfront, it becomes easy to chase deals that look good on paper but do not fit your risk tolerance.
A helpful buy box should include:
When you know your buy box, underwriting gets easier and faster. It also helps your broker narrow the search to properties that truly match your plan.
One of the biggest mistakes new buyers make is treating the listing’s advertised rent as the full story. Strong underwriting starts with a simple chain: gross scheduled rent, less vacancy and credit loss, plus other income, less operating expenses, equals net operating income, or NOI.
NOI is important because it shows how the property performs before debt service, capital expenditures, and income taxes. Operating expenses can include property taxes, insurance, utilities, repairs and maintenance, management fees, payroll, and legal or professional fees. If you skip or underestimate these items, the deal can look much better on paper than it does in real life.
Local market figures are useful, but they need context. Census gross rent includes contract rent plus utilities and fuel. That means the city or county median gross rent is not the same thing as the base rent shown on a rent roll.
This is especially important when comparing properties where utility responsibilities differ. If one seller pays water and another property bills utilities differently, the rents may look similar while actual NOI is not. Always verify who pays what.
Cap rate is commonly described as NOI divided by market value or sale price. It can be useful, but only when the comparables are truly alike. The most helpful comps are similar in location, property type, condition, unit mix, income stability, and expense reliability.
That matters in Hattiesburg because city averages, county averages, and 39402 figures do not all tell the same story. A small multifamily property in a stronger-income pocket should not be underwritten the same way as a property in a different submarket. Neighborhood-level and parcel-level diligence still matter.
Property taxes can make a meaningful difference in NOI. Mississippi says class II real property is assessed at 15% of true value, and the tax bill is calculated from true value, the assessment ratio, and the local millage rate. Lamar County’s 2024 to 2025 total millage is listed at 116.95 mills.
Using the state’s method, a $250,000 class II investment property would produce roughly $4,386 in annual ad valorem tax before exemptions or special adjustments. That is a real line item, not a footnote. If you leave it out of your analysis, you may overestimate cash flow.
Taxes are due on or before February 1 for the preceding assessment year. Mississippi also revalues property at least once every four years, and unpaid real estate taxes can lead to tax sale. For a buyer, that makes prorations, reserve planning, and tax review part of smart acquisition diligence.
With small multifamily, zoning is not something to check after you are under contract and hoping for the best. In Hattiesburg, it should be part of your first-pass review. The city requires a pre-application review for new development, redevelopment, or expansions for commercial or multifamily-zoned properties.
Site plan review is also required for new development, expansions, or redevelopment, except for single-family detached dwellings. If you are buying an infill site or thinking about adding units or making major changes, that process can affect timeline, cost, and feasibility. It is better to know that before closing.
The code says multifamily buildings on infill sites in residential districts should be designed to blend with surrounding single-family residential buildings as much as possible. For buyers, that means exterior design, parking layout, and general site feasibility are part of due diligence. These are not just cosmetic details.
If you are buying an existing small multifamily property, you should still confirm zoning, parking, and any prior site or permit history. Clean documentation can also help later when you refinance or sell.
Many small multifamily opportunities involve older housing stock. That can create upside, but it also raises the stakes on inspection and repair planning. Deferred maintenance can hurt occupancy, increase turnover, and weaken resale value.
Mississippi housing guidance says landlords must comply with local and state building and housing codes, maintain the unit in substantially the same condition as at lease start except for ordinary wear and tear, and repair defects that affect health and safety. If a landlord does not complete a repair after 30 days of written notice, the tenant may have specific remedies under state guidance. That makes pre-closing condition review especially important.
For units built before 1978, lease paperwork should include lead-based paint disclosure language. If you are evaluating older duplexes or apartment buildings, that should be part of your file review. It is another reason to look beyond surface-level numbers.
A good small multifamily purchase is not just about buying well. It is also about operating well after closing. You need a realistic plan for repairs, leasing, tenant communication, expense tracking, and deposit handling.
Mississippi guidance says landlords have 45 days after move-out to return the deposit, though deductions may be made for rent owed or reasonable cleaning and repair costs if provided in a written itemized notice. Clear records matter here. If you plan to own for several years, strong systems will make both operations and resale easier.
A simple post-closing operations plan should include:
Even if you plan to hold long term, every purchase should have an exit story. Buyers and lenders tend to value properties with stable, well-documented NOI more favorably than properties with messy records and uncertain performance. That is especially true for smaller multifamily assets where every vacant unit has a larger impact.
The cleanest resale package usually includes a trailing 12-month income statement, a verifiable rent roll, consistent expense categories, and clear zoning and permit history. Properties with utility leakage, deferred maintenance, unpredictable vacancy, or weak bookkeeping often face more pushback. Good exits usually start with good habits.
If you are just getting started with small multifamily in Hattiesburg, keep your attention on the basics. You do not need a perfect property. You need a property that makes sense in its location, supports realistic rents, and does not surprise you on taxes, zoning, or condition.
Focus on these five checkpoints first:
That kind of discipline can help you avoid common first-deal mistakes. It can also help you move with more confidence when the right opportunity appears.
